The issue with the counterclockwise position not being fully off probably has to do with the pot. If you turn it down, then measure the resistance from the wiper to ground, you'll probably find some tiny amount. Ideally it should be zero, but not all pots will get you there. You know, I did this la...

That's a great explanation. I had kinda guessed to myself that active reamps have a transformer which was probably a big part of the cost...good ones ain't cheap.

Also, not to be a thread hog, but... For the record, I put mine together last night (the variable version with the 100k pot) and it actually works really perfectly...although the pot is not working as it was "supposed" to in theory: allegedly with the pot all the way counterclockwise it was supposed...

...is the circuit described on http://www.epanorama.net/circuits/line_to_mic.html basically a very simple, low feature re-amp device? That's actually a REALLY good question and it made me realize that essentially what I've been trying to make this whole time IS a passive re-amp device ...although I...

I'm going to stud-mount a Floyd Rose tremolo to the circuit's outer housing and ground to that.

Nice! So just:

? Input jack "tip" to pot input.
? Pot wiper to output jack "tip".
? Input/output jack "sleeves" tied together and tied to pot ground as well.
? No second resistor at all.

Correct?

Ha! I won't keep you from your flame war...we'll discuss math some other time after I've had a Red Bull. Regarding your question... I just looked at the MicroMASS, and it raises one question: It says that it works as a dummy load with the attenuator controls all the way down, which looks like it wou...

Okay I understood some of that.... The place I found the original schematic (the one I posted yesterday was re-drawn by myself just to make it very clear where things are going in/out of on the potentiometer) did not make any mention of whether it as audio taper or not so you're probably right...it ...

Or make the thing adjustable. Grab a 100K audio taper pot. Signal goes into the clockwise end, comes out the wiper. Ground the counterclockwise end. Tada - variable L-pad. The 100K pot will be large enough to present a minuscule load on the output stage, and you'll probably run it about 1/4 open, s...

Awesome, awesome info...I totally get it. Thank you. Gods I love TapeOp. I posted this question on several forums: this one, gearslutz, and a couple of other forums that are more specifically focused on guitar electronics. This thread and the gearslutz one have given me some great on-target advice. ...

Or make the thing adjustable. Grab a 100K audio taper pot. Yeah I've seen schematics for this approach too. Question: does the potentiometer compromise the sound in any way versus a hard-wired resistor? I ask this out of ignorance...not because i've actually heard anything of the sort either way. M...

I'd put him up there with Leo Fender and Pete Traynor. If you want to know what the Herzog sounds like go dig up American Woman by the Guess Who. That's a Herzog on the solo. Yeah what's up with those amazing unheard of Canadian amp makers? I have a Traynor YBA-1 and it RULES! I did the Plexi mod t...

That said, I just found elsewhere what I think is the more DIRECT answer to my question...if I had properly worded it to begin with: I need to build a simple attenuator circuit that brings a line-level signal (either +4 or -10 depending) down to "mic level". Which is similar to what I was calling "g...

Wow that is some buttloads of amazing info on a brilliant amp designer I'd never even heard of! Great...now I have to collect GARNET amps, too! Thanks. This guys sounds like an incredible innovator and the circuits sound as if they are unmatched today is some ways. I want a BTO!!! It DOES claim on t...

Crazy "Amp in a box" idea: need help...

Hey Folks...semi-newbie circuit-builder here....thanks in advance for listening. It's kind of a loooong explanation but I think this might be a really cool idea if I could get some help, so please read on if you can stomach it... I was just curious: I have this craaazy idea of basically using a low-...
